Looking for info on this machine.

[spazin]

here are some more pics that might help...there are two buttons (brass) on the bottom and i took pictures before and after. the one on the right moves the brass tube on the top left up and down releasing balls that made it into the prize section. the button/brass thingy on the left moves a metal section of the slide which in turn blocks the flow of any balls from going into the spring/tube.

I am gonna try what you just mentioned too...
